Every site edit command
This is the full set of commands the site builder understands, each shown on a real site. You never type these names. You ask in plain language and your AI assistant runs the right one. They work in any assistant connected to the YG3 MCP, including Claude and ChatGPT. Every change stages to a private preview first and only goes live when you publish.
Each clip below is the command being performed on the Rivertown Plumbing demo site, with the request and the underlying tool shown on screen.
Add a section
add_block adds one section to the page. There are seven section types, and you add them by asking for what you want. Each one has typed fields with sensible defaults, so a single sentence is enough to start.
Hero
The top of the page: a headline, a short line, a primary button, and an image.
“Add a hero with our name and a 24/7 message.”
add_block: hero
Services
A grid of what you do, each with a title, a description, and an optional photo. Choose two, three, or four columns.
“Add a services grid with our three services.”
add_block: services
About
Your story or who-we-are, with an optional image.
“Add an about section.”
add_block: about
Testimonials
Customer quotes, each with an author and an optional role or location.
“Add testimonials from our customers.”
add_block: testimonials
Call to action
A focused banner that drives one action, such as calling or booking.
“Add an emergency call-to-action banner.”
add_block: cta
Contact form
A lead-capture form. Every submission becomes a lead and emails you. You choose the fields and the address to notify.
“Add a contact form so people can request service.”
add_block: contact_form
Blog feed
A grid of your most recent blog articles, pulled live from your blog. When the built page becomes your home page, add this so the articles your platform writes stay on the home page. It shows nothing until you have published posts, so it is always safe to include.
“Keep our blog articles on the home page in a blog section.”
add_block: latest_articles
Edit a section
update_block changes any field on a section you already have. Headlines, copy, images, button labels, columns, anything the section exposes.
“Change the hero headline to ‘Tampa’s 24/7 emergency plumbers.’”
update_block
Reorder sections
reorder_blocks changes the order of the sections on the page.
“Move the emergency banner up, right under the hero.”
reorder_blocks
Remove a section
remove_block takes a section off the page. Like every change, it stages first, so you see it before it is live.
“Remove the about section for now.”
remove_block
Set the business details
set_business_profile holds your name, phone, address, hours, service area, Google Business Profile and review links, booking link, social links, and licenses. The header, footer, and contact section all read from it, so you set these once and they stay consistent everywhere.
“Update our phone number to (813) 555-0199.”
set_business_profile — watch the footer update.
Change the brand color
set_blog_theme with the color setting restyles the whole site to your brand color, coherently.
“Change our brand color to a deep teal.”
set_blog_theme: brand_color
Change the font
set_blog_theme with the font setting switches the typography to any font from the curated list.
“Use a more characterful font.”
set_blog_theme: font
Find photos
search_stock_images finds free, professional photos for any section. Ask for what you want and your assistant drops it straight into the page.
“Find a different hero photo of a plumber at work.”
search_stock_images → update_block
Publish
publish_site_design makes the staged changes live. It confirms the exact changes first, then publishes, and records who published. Until you run this, everything you have done is a private draft only you can see.
“Looks great. Publish it.”
publish_site_design
See the current design
get_site_design is the read command. Your assistant uses it to see what is published, what is staged, and what it is allowed to change, along with a link to the current preview. You rarely ask for it by name. Just ask “what does the site look like right now?” or “what can I change?” and it reads this first.
